Where can I find the console or debug output from code executed in the package manager window?
ef-code-first ef-migrations entity-framework nuget
Question
I'm using EntityFramework code first with migrations. From the package manager console, I'm running "update-database". This executes Configuration.Seed(context) which I have overridden.
protected override void Seed(WebContext context)
{
Console.WriteLine("Console Test");
Debug.WriteLine("Debug Test");
Trace.WriteLine("Trace Test");
}
Where can I find that output?
Better yet, How do I output back to the package manager window?
Thx, Dan

Where can I find that output?
Sorry, but the quick answer is basically nowhere.
To be precise at least not in the package manager console.
Debug.WriteLine("Debug Test");
Trace.WriteLine("Trace Test");
You can see the output of the Debug... and Trace... methods if you attach another Visual Studio to debug the Visual Studio instance which is running the update-database command. Then in the debuggin VS you can see the output in the Output Window.
Console.WriteLine("Console Test");
You can see the output of the Console... methods if you run the migrations with the
migrate.exe command line tool which comes with EF:
How do I output back to the package manager window?
I have here also bad news, after a quick "reflectoring": with the current implementation of the EF migrations it's not supported to display custom information during execution of the update-database (or any other command).

A quick hack I use to be able to quickly find a value in my Seed method is simply to throw an exception with a value I care about, e.g.
throw new Exception(yourValue);
This errors out the Seed, but my exception/value appears in my package manager console.
